I've had the compilation of MAME stopped since one or two major revisions (now again with 0.168) on lucky8.lay without any error message, just hanging on make.exe.

This is with latest, updated official build tools on Windows 10 x64, clean build from current GIT.

It's always lucky8.lay, on different machines.
